▎ 摘　　要

NOVELTY - A nano-material modified fluorocarbon resin stone waterproof coating comprises a resin raw material comprising 70-90 %mass vinylidene fluoride resin and 10-30 %mass acrylic resin, multilayer graphene oxide having a thickness of 4-20 nm, a diameter of 5-10 mu m, and a purity of greater than 99.5 wt.%, a silane coupling agent, 0.5-1 mg/L dibutyltin dichloride, and a solvent. The mass ratio of resin material, graphene oxide, silane coupling agent, and solvent is 2-4.5:0.1-0.3:0.02-0.04:95-98. USE - Nano-material modified fluorocarbon resin stone waterproof coating. ADVANTAGE - The coating has excellent transmittance, glossiness, hardness, wear resistance, durability, and impermeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of coating, which involves dissolving vinylidene fluoride resin and acrylic resin, silane coupling agent as crosslinking agent, dibutyltin dichloride as catalyst, and multilayer graphene oxide as modifier in a mixed solvent, and dispersing at high speed for 3-5 minutes at room temperature.
